Title: Device and method for cleaning telephone number list
Inventor: UTSUMI KATSUNORI
IPC: H04M1/27457
Filed: 1996-06-25
Granted: 2004-10-19
Abstract: A cleaning system retrieves a telephone number from a telephone number list to regard as a called party number and sends a SETUP message to the network, in which an unrestricted digital information is designated as a bearer capability. In case that an ALERTING or CONNECT message is sent back from the network, the system sends a DISCONNECT message to the network immediately to perform a clear sequence and determines the telephone number effective. In case that a DISCONNECT message is sent back from the network as a result that a call has not been accepted, the system also performs a clear sequence immediately and determines if the telephone number should be treated as an effective number or a null number according to the cause content sent from the network.

Title: Information carrier and recording device for recording an information carrier
Inventor: MIMNAGH WINSLOW MICHAEL
IPC: G11B7/24097
Filed: 1996-09-24
Granted: 2011-08-09
Abstract: The information carrier according to the invention is of an optically inscribable type, such as a CD-E or CD-WO. Information can be recorded as a track of patterns on the information carrier. The manufacturer has provided the information carrier with carrier information, for example, information about the write power to be used. It is desirable for the patterns to have constant dimensions, irrespective of the velocity at which they are recorded. The recording process in which the recording is effected is therefore to be adapted to the recording velocity. In order to attune this adaptation to the information carrier, the latter contains velocity-related information indicative of the recording process related to a recording velocity, for example, a reference velocity (V1-V3), while the remaining recording parameters (W1-W3) are given for a minimum and/or maximum recording velocity at which the information carrier can be recorded. The device reads the velocity-related information from the information carrier and adapts the recording process to the recording velocity that must actually be used.

Title: Process for producing commingled polyurethane-urea and dissimilar polymer hydrogel coatings
Inventor: DING NI
IPC: A61L31/10
Filed: 1996-01-15
Granted: 2003-04-15
Abstract: A process for preparing coating compositions of a commingled hydrogel of a polyurethane-polyurea polymer hydrogel and a poly(N-vinylpyrrolidone) polymer hydrogel; a process for making materials composed of a polymeric plastic or rubber substrate or a metallic substrate, with a coating of the commingled hydrogel thereon; and a process for making medical devices with a coating of the commingled hydrogel thereon, are disclosed. The coating compositions tenaciously adhere to the substrate materials and medical devices to which they are applied due to bonding of a tie coat to a reactive substrate surface and due to the commingling of the two hydrogel components. The coating compositions and coated materials and medical devices are non-toxic and biocompatible, making them ideally suited for use in applications such as for catheters, catheter balloons and stents. In such applications, the coating compositions, coated materials, and coated medical devices made therefrom demonstrate low coefficients of friction in contact with body fluids, especially blood, as well as a high degree of wear permanence over prolonged use. The commingled hydrogel coatings are capable of being dried to facilitate storage of the devices to which they have been applied, and can be instantly reactivated for later use by exposure to water.
